Latent tuberculosis in pregnancy: screening and treatment.

Abstract

Currently, most cases of active tuberculosis in the United States are a result of activation of latent tuberculosis infection. In this article, the history of the epidemiology of tuberculosis and latent tuberculosis infection is reviewed. Previous and current recommendations for screening and treatment for latent tuberculosis during pregnancy and the postpartum period are discussed. A review of the literature regarding postpartum and antepartum treatment is included. Finally, the question of whether antepartum or postpartum treatment is the most beneficial is discussed.
